SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed November 21, 1917. Serial No. 203,086.

To all whom it may concern:

Be it known that I, EUGENE CARPENTER, a citizen of the United States,residing at Oak Bluffs, in the county of Dukes, State of Massachusetts,having invented a certain new and useful Improvement in SurgicalInstruments, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to tools or instruments for applying cleansing ordisinfecting solutions, or medications, tosores or diseased tissueslocated in subcutaneous portions of the body, or in inaccessible orhidden positions therein.

More especially my invention consists in an instrument of the characterdescribed by which such solutions or medications may bealternatelyintroduced into the place under treatment, and then withdrawntherefrom; with the capacity of repeating fresh applications andwithdrawals as many times as desired; all these results being efl'ectedwithout removal or shifting in position of the instrument, but merely bythe manipulation of suitable means with which my instrument is provided,and preferably operable by the pressure of a finger or thumb.

My invention finds one of its principal applications in dental work forthe treatment of disease in. the alveolar process or of ulcers or soreslocated near the base of the'tooth or in the jaw. I have in consequence, in this application, shown and de-- scribed my invention asembodied in an instrument designed for this especial use, without,however, thereby intending to limit its use in such manner.

invention is shown in one of its preferred forms in the drawings whichform apart of this application and is described in this specification byreference to such accompanying drawings.

In said drawings,

Figure 1 shows, in medial longitudinal section a-dental instrumentembodying my invention.

Fig. 2 shows a side elevation of said instrument, partly in section.

Fig. 3 is a view in section on an enlarged scale showing the introducingnozzle of an instrument designed for dental work, in operativ'e'positionwith respect to atooth under treatment.

Fig. 4 shows an introducing nozzle more especially designed for thetreatment of boils, hypodermic sores, or the like; the same being shownon a somewhat larger scale than the nozzle in Fig. 1.

Referring to the drawings,--

1 represents the body of the tool or instrument, preferably composed ofpulp or other suitable material molded into shape while in a plasticcondition, and thereafter allowed to set or harden. Traversing the bodyof the instrument are channels preferably embodied in pipes bent toshape and positioned in the proper location in the mold in which thebody is shaped, so as to become permanently incorporated in the plasticmass of which the body is molded. Said channels or pipes are disposed asfollows: Pipe 2 leads from an external position 2, forming 'an extensionadapted to receive a flexible hose pipe 3 and emerges from the threadedboss 4 which is located in the central part of the body. Pipe 5 alsoemerging from the same boss 4: leads to a port, 5, opening through thewall of a valve chamber, which contains the valve 6 preferably axiallylocated in the forward part of the body. Pipe 7 leads from port 7 alsoopening into said valve chamber, to an external extension 7 locatedpreferably at the rear of the body and adapted to receive the hose 8.

Said Valve 6 is preferably arranged to slide longitudinally within, andin leakage proof relation with respect to the walls of the valvechamber, and is provided with appropriate means, hereinafter to bedescribed in detail, by which longitudinal position of said valve insaid valve chamber may.

be controlled. By preference the forward end of said valve is providedwith a projecting portion 6 of reduced diameter, adapted to slide inclose fitting relation within alongitud'inal hole 9 leading to the endof the tool where an introducing nozzle 10 is carried at the end of thetool by a ball and socket joint or by other means calculated to permitangular adjustment in position with respect to the body.

A passage 11 extends throughout the length of the introducing nozzle,and in forming the ball and socket joint by which said nozzle isattached to the tool end, suitable provision is -made so thatthesaidnoz- V wardly throughfacutaway portion'of the tool-body and engageswithin a slot 15 example 6 zle passage is in communication with saidlongitudinal hole 9 during its entire range of angular adjustment. V

The valve 6 is provided with an interior passage 6 traversing the valveextension 6 and extending rearwardly through the body of the valve for aportion of its length; then branching outwardly to outlets 6 and 6located on the circumference of the valve. The location of the valve inthe valve seat, and of the said branch outlets in the valve are soarranged in position with respect to the ports 5 and 7*, that at theforward limit. of movement of the'valve 6 one of said outlets, asforexample 6, is in registration with the port 5 ,]at' the rearward I limitof movement the other outlet, as for a is in registration with the port7*. V

. The preferred mechanism for controlling the operation of the valve 6is as follows:

A T -sha'pe'dlever 12 is pivotallyicarried onthe pin 13 mounted in ears14: formed on forming a [part ofsaid lever, extends'downformed inftherear end of the valve :6. The

extreme end of said arm 12? bears against a spring 16; which springpreferably has depressions formed therein. When said lever end 12 restsin the central depression on the spring the relation of operating parts7' is such that the valve is positioned in the neutral or inoperativeposition. When said lever end is positioned in the depression in frontof said central depression the valve is so located thereby as to bringthe valve 6 outlet 6 in registration :withthe port 5' 4O H V V a V-establ1shmg; IGOIHIIlllDlCfltlOIl between pipe -5' and the passage ofthe introducing nozzle.

When the lever end is positioned in the depression at the rear ofthesaidcentral'depression the'said' valve is positioned so'a's f;to br ng thevalve outlet 6? in registration 'with. the port 17?, establishingcommunication between the pipe? and the passage of 5o 7. the exterlorjofthe boss" 41preferablyby a the introducing nozzle. 1'- 4 g A container17 is provided which engages -pipe thread connection, so asftohe-mounted vided and is connected with the pipe 2 by 7 upon said boss 4ma leakage proofrelation.

"When so mounted'theends'ofjthev pipes 2 and: 5' are located in theinterior of the container. The container-is preferably pro- A source ofpressure (not shown in the l means of "a preferably flexible tube 3attached to the'glextension 2 p In similar man- -'ner a vacuu-mproducng'source (not shown 1n'the.draw1ngs,)'1s connected by means of drawingsbut of any approvedtype) is pro- 7 a tube 8 engaging the extension end 7ofx the pipe 7.

The manner of using my device is deof thealveolar'process, 19Vl0cated atthe base thereofwithin the jaw;-a portion of which jaw isindicated at20. A suitable channel 21 having been previously prepared in said tooth,leading to the diseased region, 7 the introducing nozzle 10 of the toolis in,

serted as far as possible within such. chan: nel a leakage proofconnection of the introducing nozzle within saidchanneliloelngesta'lolished by the action of a packing washer 22 (which may beadjustableso that the end V of the introducing nozzle 7 may extend 3through the packing washer or be flush with it as desired) provided atthe end of the introducing nozzle.

When the tool is in the desiredposition Q the rearward end of, thecontrolling lever'1'2 V is depressed, throwing the valve 6 into theforward position, wherein it establishes communication with the pipe 5and theintroducring nozzle. Thereupon, the tool being held so that theopen end 5 of the pipe5 will extend downwardly into and'be submersed insure transmitted from the source of pressure through the hose 3' andpipe 2' to the interlor "of the container 17 will force a portion of thecontents of the container into'the region of the tooth under treatment;a suflicient desaid contents as is shown in Fig. 1, the pres gree Ofpressure being employed to insure that the solution or medicationpenetrates to the place under treatment. Y i 7 ""After the expiration ofthe period rej quiredto allow the solution or ,medication to act,the'forward end of the controlling lever V is depressed, throwing thevalve'6 into; the

position wherein it establishes communicae tion between the pipe 7 andthe passage of the introducing nozzle: In su'ohvalve position the.solutionjust previously introduced will bejsuckedoutand removed fromthe place under treatment? Thereafter by suite 7 able manipulation ofthe valve controlling I lever a fresh supplyoffsolution or medicationmay be forced to the part :under treatment and later removed, andthisprocess of introduction and removal may be continued withoutdisturbing the position of theinso long as a supplyiremains in thecontainer strument. It should benotedthat the necessary manipulationscan readily be effected by ment is heldin operating-position f;W here asubcutaneous'sore, as for example" a boil or ulcer pocket, is to betreated, I employ an introducing nozzle in the general-I30 form of astiletto point terminating in a perforated end having the usualcharacteristics of a hypodermic needle. Said stiletto point is of suchdimensions as to permit the needle end of the same to be introduced intothe interior of the boil or ulcer pocket by penetrating the fleshtissues by which the same is inclosed; my idea being to obtain accessthrough the ulcer wall to the said interior by the stretching orpressing away of the nerves and other fibers embodied in the tissues ofthe said wall adjacent the point of penetration as distinct from thecutting or lancing of the same, which would sever many small nerves notliable to reunite again when the cut healed. When the stiletto point hasbeen so introduced, the boil or ulcer pocket may be interiorly flushedwith cleansing solutions or treated with medications by alternateapplications and subsequent withdrawals thereof, effected by themanipulating of the valve lever in the same general manner as has beenhereinbefore described.
